PART 1: well my vit had been making a horrid noise and narrowed it down to wheel bearings, thought i would do a write up. this is how how i did it, if anything is incorrect please add ur opinion.
jack up the front end, place on jack stand and remove wheel.
next is to remove the caliper, there are 2x 17mm bolts that hold it on. they will be tight.
move caliper to the side and out of the way.
remove brake disk, i used a soft faced hammer. just tape it and rotate then tape some more and it will come off.
next thing, is to remove the free-wheeling hub. it has 6x 12mm bolts.
showing this
remove the 4 screw carefully, they round off easily so hit screw driver into them before trying to undo.
exposing this:
now, you can either use a special socket or use a punch and a hammer
these will be VERY tight, i almost gave up. if you cant move it by hitting one of the holes, try another and it may help. if not, get a bigger hammer 
once the retaining ring has been wound off, you should be able to give the hub a yank and it should come off.
this little ring will sit between the bearings and the retainer.
at this stage, you need to press out the bearings, remove the seals and you will see a cer-clip, remove this first. i took it to work and did it. depending on the condition of the bearings you could do it with a small 6t press but could take up to 20t. these bearings are new (installed w.e before) but my hub was rooted. so i got a new hub and seals. end of part 1.....
